With owner Ahmed Zayat watching from the Del Mar grandstand, American Pharoah posted another workout Thursday ahead of the Aug. 2 William Hill Haskell Invitational.

The Triple Crown winner went five furlongs in 59 seconds flat on trainer Bob Baffert's watch, completing another move he made look easy under exercise rider Martin Garcia. Clockers officially credited him with six furlongs in 1:11 flat -- fastest of seven -- before galloping out a mile in 1:38.40.

Baffert told the Daily Racing Form after Thursday's workout, "He's getting faster. I'm getting goosebumps." Reporter Jay Privman noted the colt was "strong, into the bit." Added Zayat in a tweet: "Gallop out was insane."

Baffert trainer plans to work American Pharoah once more before the Haskell and ship out the Wednesday of race week. A flight is then scheduled to bring him back to Del Mar after the race at New Jersey's Monmouth Park.

Another spot between the Haskell and Oct. 31 Breeders' Cup Classic at Keeneland hasn't been determined, though the Aug. 22 TVG Pacific Classic at Del Mar, Aug. 29 Travers Stakes and Saratoga and Sept. 19 Pennsylvania Derby at Parx appear the most likely candidates.
